I have always suspected that there was a DIY Ground Glass technique, thank you for post it this.

[@mhaustria]

you are welcome - enjoy and let me know if you have any questions

Hello. Thank you for your recipe for making frosted glass for a 13 * 18 camera. I made a focusing screen for my camera using a 400 + 600 image, the result is excellent

[@mhaustria]

You are very welcome! That’s quite a huge camera! Enjoy shooting with it!

[@jass4team823]

Awesome Dear Markus Hofstätter Really appreciate the DIY

[@mhaustria]

Thanks a lot! Happy I can help!

[@hiltsyartnstuff1142]

THANK YOU! Just got a Kodak N0. 2 5x7 (a family heirloom) with missing ground glass, and it turns out I have everything I need to do this! the camera needs some love and a better lens but I'm going to get it in shooting condition and probably do some paper negative stuff and maybe some wet plate in the future. brobably need to make some more film backs as well.

[@mhaustria]

Hiltsy ArtNstuff very welcome - I just searched for it and it looks like you got yourself a beautiful camera. Enjoy! If you need to modify a plate holder for wetplate, have a look at this video: kzbin.info/www/bejne/qIfbh2qHic-kmNk

[@mrpresident7121]

Simple and helpful, thanks!

[@mhaustria]

Very welcome - will make a new one myself soon

[@petemc5070]

Great job.

[@mhaustria]

Thanks a lot!

[@sundarAKintelart]

Pretty good. A glass from a discarded flatbed scanner would be good for making a ground glass.

[@mhaustria]

Thanks, that’s a great idea, just not sure how thick it is and if it will fit. I dismounted mine for cleaning last year and it looked pretty thick

[@sundarAKintelart]

@@mhaustria... Umax Astra models have thinner glass. Not measured though.

[@ssldr4526]

A great easy to follow video so much so I’m going to try and make a screen for a 45. When you rub the grit in between the glass does the motion have to be in the same direction to get the smooth finish. Thanks

[@mhaustria]

S sldr thank you, I never thought about it, but I did

[@ssldr4526]

thank you I shall give it a go and check out the rest of your videos

[@mhaustria]

S sldr welcome and thanks - if you need a lens cap, there is a video for that too :)

[@sundarAKintelart]

Nice. Something to consider here. If the glass is ground with finer grit beyond a point, it would be difficult to focus. I think the 600 grit used here is good enough. No finer than this.

[@mhaustria]

I agree! 400grit by itself makes it more contrasty.

[@on8mil]

brilliant many thanks

[@mhaustria]

very welcome - thanks for commenting!

[@gabrysgabriukas]

Hi, thanks for the video. Which side should I put it to camra. Grounded to lens? In my old camera ground glass side was is in front..

[@mhaustria]

very welcome - you put the grounded side to the lens

[@jurekustrin6087]

Congratulations!!!

[@mhaustria]

Thank you!!

[@GONZOFAM7]

Brilliant

[@mhaustria]

Thanks a lot!

[@studio-gh]

fantastic !! no fluorhydic acid used ?

[@mhaustria]

guillaume d'hubert thank you. I just used the powder as described. Super easy to do.

[@sanelendlovu1893]

This is so cool 😎 Thanks!

[@mhaustria]

Sanele Ndlovu very welcome - glad you like it!

[@UpcomingJedi]

I had to do this for my homebuilt 5x7 pinhole camera

[@mhaustria]

@@UpcomingJedi I think it’s always worth it to build one by yourself

[@nickfanzo]

So my ground glade shattered this morning due to a tripod fail. Very upsetting 😢 BUT thanks to your video, I bought some glass and I am making my own right now. Looks good. I am using sharpening hones and other stones since I have them and don’t have sic powder in the area.

[@mhaustria]

Nicholas Fanzo happy I could help. Just curious, what kind of sharpening stones do you use?

[@nickfanzo]

Markus Hofstätter well I shave with straight razors, so I have many, I just used a carborundum, it did ok, powders would be better.

[@crocato]

Thanks

[@mhaustria]

Happy to help!

[@TomChamberlain]

awesome. thanks

[@mhaustria]

Thanks a lot - my pleasure

[@oldschoolcollodion]

Markus I am needing to make ground glass. My question is, can you over grind the glass?

[@mhaustria]

No, I really don’t think so.

[@Austrianoak07]

v interesting 👍🏼

[@mhaustria]

Thanks!

[@myatminsoe9282]

Bro, is there any substitute for silicon carbide?

[@mhaustria]

you could try it with some wet sandpaper - not sure how it goes. But start with 400 grain one

[@kavemankameras]

Hint - Do This in the bathtub--put a washrag under the glass for support. All the mess washes right down the drain ...

[@mhaustria]

Larry Pulliam great Idea! Thank you

[@phillipkearney520]

The bottom plate will become concave ,it my be wise to flip them now and then .

[@mhaustria]

What plate you mean?

[@phillipkearney520]

@@mhaustria the bottom plate , the principle of grinding a optical Flat .

[@mhaustria]

Phillip Kearney you mean during grinding to flip the plate upside down? Thanks, that makes sense!

[@phillipkearney520]

the bottom sheet of glass becomes more concave and the top convex it may not matter but just a thought .cheers

[@phillipkearney520]

@@mhaustria Yes .

[@youarenotaghost3702]

Seems like you could end up with almost two ground glasses by the time you're done.

[@mhaustria]

I actually did two :)

Woodglut has very good designs and plans.
